Well, the whole system-config-networking scheme is pretty well
deprecated these days, but yes it maintained configurations in
/etc/sysconfig/networking. The idea I believe was that you could have
different "configurations" based on the same underlying hardware and
switch between them. The hard links maintained compatibility with the
basic ifup/ifdown scripts.

I believe it is used by the NetworkManager system to uniquely identify
connections. See output of "nmcli c".
